who has had some experience or
training as a printer. The expense per pupil for equipment, for the
space it occupies, and for instruction renders special training for
such small classes impracticable. All of the skilled occupations, with
the exception perhaps of the machinist's trade, are in the same case.
An attempt to form separate classes for each of the eight largest
trades in the city would result in two classes of not over five
pupils, three classes of not over 10 pupils, and only one of over 13
pupils. The following table shows the number of boys, in a school of
this size, who are likely to enter each of these trades.

_Number of boys who will probably become:_
Machinists 36
Carpenters 13
Steam engineers 11
Painters 10
Electricians 9
Plumbers 7
Compositors 5
Molders 5

A GENERAL INDUSTRIAL COURSE

The members of the Survey Staff were, however, of the opinion that
through the system of electives in the junior high school, industrial
training of a more general type, made up chiefly of instruction in the
applications of mathematics, drawing, physics, and chemistry to the
commoner industrial processes, would be of considerable benefit to
those boys who, on the basis of their own selection or that of their
parents, are likely to enter industrial pursuits. A course of this
kind is outlined in following sections of this chapter.

The objections which may be brought against this plan are frankly
recognized. It takes into account only the interests of the industrial
group, comprising less than one-half of the boys in the school.
Unquestionably it would tend to vitalize the teaching of mathematics,
drawing, and science for the boys who enroll in the industrial course,
but it leaves unsolved the question of method and content of
instruction in these subjects for the boys in the non-industrial or
so-called academic course. Very possibly future experience may
demonstrate that the plan recommended for the general industrial
course affords the best medium for teaching science and mathematics at
this period to all pupils, in which case a differentia
